Portsmouth chief executive Peter Storrie admits the club would be keen to sign Mark Viduka, but is wary about a deal for Amr Zaki.
Following the sale of Peter Crouch to Tottenham, and the expected departure of David Nugent, Pompey are in the market for a new striker.
Frederic Piquionne has arrived on loan from Lyon, while Pompey boss Paul Hart has been linked with moves for Viduka and Zaki.
Viduka is currently a free agent after leaving Newcastle United and Storrie admits a deal could be done if the Australian proves his fitness.
"A fit Mark Viduka is still a very, very good experienced player and this is a special year for him because he has the opportunity to captain his country in the World Cup," Storrie told The News.
"We would be fools not to want Mark here. But at the moment he's still on vacation as I understand it.
"We would have to see what his fitness levels are like and how long it is going to be before he is fit.
"You never know, he might have been working out right the whole way through and be pretty fit. So of course he would interest us."
However, Storrie was less convinced about the merits of pursuing a deal for Egyptian ace Zaki, who spent last season on loan at Wigan Athletic.
He added: "That is mainly agent talk. The agent has been on to me constantly about him, and out of respect we always look at things like that.
"The boy has had some issues and - despite the Portugal weekend - we generally have a very, very happy camp in terms of the players. It's a good relationship.
"With Zaki, firstly we would need to be sound and positive about the deal and, secondly, we certainly wouldn't pay any loan fee until we knew what the stability of the boy was like."
